TRANSMISSION MECHANISM.

Application filed May 9, 1914.

To all whom it may concern Be it known that I, HENRY J. Herman, a citizen of the United States, residing at Carroll, in the county of Carroll and State of Iowa, have invented a new and useful Transmission Mechanism, of which the following is a specification.

The invention relates to improvements in transmission mechanism for traction engines.

The object of the present invention is to improve the construction of transmission mechanism and to provide simple, practical, and efficient mechanism designed for traction engines for operating agricultural machinery and for moving plows and for various traction purposes, and equipped with a motor carrying a gear element arranged to directly engage friction disks, and adapted, through the adjustment of the motor, to varythe speed of the transmission gearing, whereby a plurality of'different speeds may be obtained from a gasolene engine or other motor traveling at a single speed.

Another object of the invention is to provide a transmission gearing arranged to cooperate with the gear element of the movable motor. so as to start or reverse the traction engine without disturbing the motor after the same has been adjusted to rotate the transn'iission gearing at a predetermined speed, and also for disconnecting the transmission gearing from the traction wheels of the engine to permit power to be taken from a driving pulley for operating various machinerv while the traction engine is station- Y fer-red. manner, is provided at its rear porarv.

A. further object of the invention is to provide a movablv mounted motor of this character adapted, through its movement, to afford ready access both to the parts of the engine and the said motor actuated gear element to enable the same to be readily repaired or renewed, and at the same time, to facilitate the ready removal of the motor from the main frame of the traction engine without disturbing the latter or theconnections between the motor and the radiator or other parts of the mechanism.

lVith these and other objects in' View the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended, it being understood that Specification of Letters Patent.

various changes in the form, proportion, size and minor details of construction, Within the scope of the claims, may be resorted to without departing from the spirit or sacrificmg any of the advantages of the inventlon.

In the drawings :Figure 1 is a side elevation of a. traction engine constructed in accordance wlth this invention. a plan vlew of the same, parts being re- Flg. 2 is moved and other parts being in section. Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2. Fig. 4 is a central longitudinal sectional view. Fig. 5 is a transverse sectional view on the line 55 of Fig. 2. Fig. 6 is a detail vertical sectional View on the line 66 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

in the accompanying drawings, in which is illustrated the preferred embodiment of the invention, 1 designates a horizontal main frame provided at opposite sides with channel beams 2 connected by suitable cross bars and arranged in parallelism and forming a guide or way at the front portion of the main frame for a longitudinally slidtion with a platform 5 for the accommodation of the operator. The platform preferably consists of spaced transversely disposed slats extending across the space between the main longitudinal beams 2 and having their terminal portions arranged upon and secured to the same.

The main frame is supported at the back by a rear axle 6, and at its front portion by a front axle 7,'a semi-elliptic leaf spring 8 being preferably interposed between the front portion of the main frame and the front axle. The spring 8, which is transversely disposed, is suitably secured at its ends of the main frame at opposite sides thereof and it has a central pivotal connection 9 with the front axis 7. The front axle is providedwith spindles 10 receiving front guiding wheels 11 and mounted to turn on vertical pivots 12. The spindles 10, which are connected'with the front axle 7 by suitable knuckle joints, are provided worm wheel 19, which meshes with a worm The 20 of an inclined steering shaft 21. worm gearing and the inclined steering shaft are preferably located at the right hand side of the traction engine, as shown, and the said inclined steering shaft is equipped at its upper end with a suitable steering wheel 22. hen the steering wheel is turned, the transverse rock shaft 13 is partially rotated, thereby moving the rocker arm 17 backwardly or forwardly and imparting a horizontal swingingmovement to the spindles of the front axle. Any other suitable steering mechanism may, however,

be employed.

The rear axle, which is rigidly secured to the main frame, is mounted in suitable bearings 23, and its spindles receive driving or traction wheels 2 1 adapted to rotate on the rear axle. The traction wheels, which may be of any preferred construction, are provided with extended hubs 25, projecting from the inner sides of the tractors or traction wheels 24-, and having mounted on them large sprocket gears 26, which are connected by sprocket chains 27 withsprocket pinions 28, mounted on the ends of a divided transversely disposed shaft 29. The chain is preferably a roller sprocket chain, but any other form of chain or gearing may be employed for transmitting motion from the divided transverse shaft '29 tothe traction wheels. The transverse shaft 291s journaled in intermediate and side bearings 30 land 31i and its sections are connected in the usual manner by clifferentlal gear ng (not shown) preferably incased 1n an enlarged hub 32 of a spur gear wheel 33, which meshes'with a shiftable pinion 3 1 of a transversely disposed transmission shaft'35. The

transmission shaft 35 is journaled in suitable bearings 36 of the mainframe, and the pinion 3 1 is provided with a groove 37, which receives a feather or key 38 of the transmission shaft 35, whereby the pinion "is slidably interlocked with the said shaft 35 and is adapted to be moved longitudinally of the same into and out of mesh with the large spur gear wheel 33. The pinion 341s moved along the shaft 35 by a shifting lever 39, disposed longitudinally of the 'main frame and fulcrumed at a point intermediate of its ends at 10 on a vertical pivot of a support 41. The support 41, which may be of any preferred construction, is suitably mounted on the main frame and the shifting lever 39, which extends rearwardly from the transmission shaft to a point within easy reach of the operator, has a forked front portion-42 provided with perforations 13 for the reception of projecting pivots 14- of a ring 45 mounted in a groove :'cdin an.ex-

tended portion. of the hub of the spur pinion 34C. The shifting lever is adapted to be oscillated to slide the pinion 34 into and out of mesh with the gear wheel 33. This willenable power to be taken from a driving pulley 47, suitably fixed to the right hand end of the'transmission shaft and adapted to receive a suitable belt to enable the traction engine, when stationary, to be employed for different belt work. Any other suitable form of gearing, however, may be employed for this purpose.

' The transmission shaft 35 is also shiftable longitudinally in its bearings. 36 to carry either one of a pair of friction disks or wheels as and 49 into engagement with a motor actuated gear'element 50 and also to arrange the said friction disks or wheels 18 and 49 out of contact with the gear element 50. This will enable either the traction en gine or the driving pulley {17, when the pinmoved longitudinally in either direction by shifting mechanism comprismg a bell crank lever 51, and an operating lever 52 connected with an arm 53 of the bell crank lever 51 .by a rod 54. The arm 53 extends horizontally rom the upper end of a spindle or pivot 55, which is provided at a'point intermediate of its ends with a forked or bifurcated arm 56.

The spindle or pivot portion 55 is journaled' in spaced bearings 57 of a transverse supportlng plate or member 58, and the arm 56 straddles a sleeve 59, which is interposed be-. tween the hub of the friction wheel 49, and

a thrust collar 60.]The sleeve 59 is ar-v ranged at the inner side of the friction disk or wheel 19 and the thrust collar is fixed to the shaft 35 by a setscrew or other suitable means in spaced relation with the said friction disk or wheel 49. Antifriction balls 61 are arranged at each end of the sleeve 59, the hub of the friction'disk or wheel 49 and the thrust collar 60 being provided with 00- V acting" grooves forming races for the antie frictionballs, Any other suitable antifric-E tion thrust hearing may, of course, be provided. The supporting plate or member 58 is suitably secured'to a transverse connecting beam 62 and the bearings for the vertical spindle or pivot portions are located at the rear face of the said supporting plate or member 58. The arm 56 extends rearwardly from the spindle in a direction longitudinally of the traction engine, and the other arm 53 of the bell crank lever is disposed transversely of the main frame and extends inwardly from the pivot or spindle 55. The operating lever 52,'which is fulcrumed at its lower end 63, is suitably mounted on the main frame and the connecting rod 54: is pivoted to the lever 52 at the lower portion thereof. The said lever 52 carries a spring actuated dog or detent 64, arranged to engage a curved rack 35 and controlled by a suitable latch lever mounted on the operating lever 52 adjacent to the handle or gripping portion thereof. lVhen the operating lever 52 is swung forwardly or backwardly, the arm 56 is swung inwardly or outwardly, and the transmission shaft 35 is moved in a corresponding direction. The dog or detent of the curved rack enables the operating lever 52 to be secured in any of its adjustments. The motor actuated gear element 50 consists of a rim of fiber or other suitable material mounted on an annular flange 66 of a fly wheel or driving wheel 66 of the motor 4:. The driving wheel or fly wheel is disposed transversely of the machine, while the friction disks or wheels are arranged longitudinally with respect to the frame of the machine. The motor shaft 67, which carries the driving wheel or fly wheel 66, is extended rearwardly and is slidably journaled in a bearing 68 of the transverse supportingplate or member 58, and it is adapted'to be withdrawn from such bearing by the vertical movement of the motor to afford ready access to the fiber rim for enabling the same to be readily repaired or renewed. The motor, which preferably consists of a four cylinder gasolene engine, may be of any other preferred type, and the subframe 3, which supports and carries the motor, comprises in its construction upper and lower longitudinal angle bars 69 and 70 and connecting posts 71. The vertical posts or standards of the subframe' are bolted or otherwise secured to vertical flanges of the angle bars 69 and 70, and the upper angle bars 69 have inwardly extending horizontal flanges upon which the motor is mounted. The lower angle bars have outwardly extending flanges which are arranged adjacent to the front guiding portions of the longitudinal beams 2 of the main frame. The lower longitudinally disposed angle bars extend in advance and in rear of the upper angle bars 69 and they are supported upon suitable transverse connecting bars or members of the main frame. The supplemental frame is also provided with a transverse plate or member 72 extending across the frame of the traction engine and detachably bolted to the lower face of the horizontal flanges of the bars 70 and projecting beyond the same to engage beneath the longitudinal guiding portions of the side beams 2 of the main frame to prevent the lifting of the supplemental frame and the motor. The radiator 73 of the motor is supported by the projecting front portions of the lower bars of the subframe, and the motor, which is adapted to be moved back wardly and forwardly on the main frame without affecting the connections between the radiator and the motor or any other of the parts of the motor mechanism.

The transverse plate or member 72 of the subframe is connected by a pair of longiudinally disposed links 7 4: with a transversely disposed lever 7 5 fulcrumed at one end 76 on the main frame and connected at its other end by a rod 77 with an operating lever 78. The links 74 are centrally arranged and are pivoted at their front ends to the upper and lower faces of the transverse plate or member 72 centrally thereof, and the rear ends of the links are pivoted to the upper and lower faces of the lever at a point intermediate of the ends thereof. The operating lever 78 is adapted to be swung backwardly and forwardly to slide the subframe and the motor toward and from the transmission shaft. By the said adjustment of the motor the speed of the friction disks or wheels, which comprise, with the gear element 50, the transmission gearing, may be varied, while the engine is operating at a single speed. As the motor actuated gear element is moved rearwardly toward the center of either of the friction disks or wheels, the speed of the same is increased, and an adjustment of the motor actuated gear toward the periphery of the friction disk or wheel will effect a corresponding reduction in the speed of the transmission gearing. In practice, the adjustment of the motor is made While the friction disks or wheels are out of contact with the motor actuated gear and after the motor has been properly adjusted, the friction disks may be moved into fric tional engagement with the motor actuated gear. When it is desired to slide the subframe and the engine forwardly to afford access to the fiber rim or gear element 50, one of the bolts of the operating mechanism is disconnected to release the subframe from the control of the operating lever and when it is desired to ent rely remove the subframe and the engine from the main frame, the transverse plate or member 72, which is en gaged beneath. the side beams 2 of the main frame, is unboltecl. This will free the subframe and the engine can be removed from the motor constitutes a closure for the open front end of the hood. The machine is also v equipped with a suitable-top supported by front and rear standards 86 arranged in pairs and forming convenient means for securing side walls 87 to the machine for forming a cab. In practice, the traction engine will also beprovidedwith suitable wheel guards 88, as illustrated in dotted lines inFigs. 1 and def the drawings, and

"a draw bar 89, which is located beneath the platform, and which extends in rear of the main frame, is pivotally connected at its front end to the. same. Also, the traction engine is designed to be provided with a suitable seat 90 for the accommodation of the operator.
